OK akready found on my own. :bigsmile: - registry issue.
I don't get how things like that can happen. :rolleyes:
For some unknown reason, the 12x speed (16160) was not present in the reg files for the NEC. 16x was, though (65535)!
Seems like the "max" speed doesn't get an actual number in the drop-down list unless all speeds are mentioned in the reg files.
So 16X scanning was actually available, but was labeled as "max".
But as the 12X wasn't set in the reg files, how on earth could I select it in the drop-down list??????
go figure... :rolleyes:
Whatever, I added the 12X speed (16160) in the reg files, all speeds are selectable now, problem solved
